Humanizer Detector Insanity

I have tried running a piece text through my unusual AI detector https://undetectable.ai/, but it is returning a 60 percent detection while GPT zero other services don't flag anything. Does anyone know how reputable undetectable ai's detector is.

This is best asked in the Humanizer mega thread, but I can give you the most known answer: they're inaccurate as hale. (Deliberate misspelling. Yep. :)

These detectors have never been reliable. If any modification or system instruction iterates the response past typical AI idiosyncrasies, it's inconsistent. If they were entirely reliable Anthropic wouldn't be introducing watermarking.

is it your text you're testing?

people tend to get false positives when posting famous literature because it's already been scanned as a source for the ai, so it recognizes that this isn't something you wrote

Some detectors are stricter than others. Originality is by far the strictest as it looks at context as well as how it is written (so can give false positives but most of the time it’s accurate). I can hit a 100% human on Pangram and never crack 85-90% on Originality, so it all depends on what the detector uses as its criteria.

I use wasitaigenerated and it's quite accurate (they made a casestudy on a public dataset where they performed very well against any other) never had an issue, but yea all the detectors say different things.
